Mr Birling's Capitalist Delusions
Mr Birling's confidence about the "Titanic... unsinkable, absolutely unsinkable" creates massive dramatic irony. The 1940s audience knew the Titanic sank, making his other predictions seem equally foolish.
The alliteration in "hard headed practical man of business" shows his unfeeling nature. Priestley suggests this heartlessness defines capitalist society as a whole.
His dismissal of the "famous younger generation" reveals his immaturity. Calling Eva's suffering and death "a joke" shows his complete lack of morality and human compassion.
💡 Key exam point: Mr Birling represents everything Priestley hates about capitalism - greed, ignorance, and total lack of social responsibility.
The Titanic metaphor works perfectly: just as the "unsinkable" ship hit an iceberg, the Birling family's "untouchable" status gets destroyed when Inspector Goole arrives with the truth.
